MACHINE FOR MAKING LACE-PAPER.

Specilication forming part of Letters Patentl No. 46,115, dated January 31, 1865.

thereof, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a plan or top view of the improved machinewhereby the lace-paper lis manufactured. Fig. 2 is a sectionbt' said Fig.- l onlinem y. f

The saine letters indicate thesaxne parts in both figures.

The nature of my invention consists n1 grindin g ott' orremoving the elevated parts of em' bossed paper by means ofa machine sub itantially as hereinafter described.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same.

I deem it proper to state that the usual inanner of making-lace paper is by pressing apiece ot' paper between two dies, one of which conta-ins the design in relief or elevated, while the other contains the design sunk or depressed. The embossed paper is removed from the dies, and the elevated parts of it are cut by hand with aknife 0r similar instrument, either by percussion or pressure.

My machine for removing the elevated parts of the embossed paper consists of a frame, D l), containing two cylinders, A and B, turning on two parallel axles, E and F, in opposite directions.

is covered on its surface with a layer of ground g1@esteemnlrasimet substance, entire., roller itsel may be ftmed of sai`d"sbstances The other cylinder, B, is provided-withaduplieate of the depressed or sunk die, upon which the embossed paper to be cut is fastened so One of said cylinders or rollers, A,

as to t neatly into the devices of the die.

The projecting portions of the embossed paper are then brought into contact with the roller A by rotating the said roller, ,whereby the elevated parts of said paper are ground off or removed.

"The said machine is so constructed that the cylinder A will-rotate with a,- 'much greater speed than the cylinder B, thev axle E of cylinder A being connected by a band or belt, m, with the circumference of iiy-wheel G, while the axle E oficylinder Bforms the axle ot" a ,toothed wheel, H, in which an endless screw, J the axle offwhich endless screw K is connected by a belt, n, with the axle L ot' the flywheel or drivingwheel G. 'Thus the rotation of the .said iy-Wheel will cause a greater speed in the rotation of the roller A than in that of roller B.

The feeding apparatus is shown on the drawings, but is not claimed in this specification.

When all the elevated parts of the embossed paper are removed byA means of this machine, t-he paper is removed from the die, and is then in a iinishedcondition as lace-paper.

The advantage et this method of making lace-paper consists in greater cheapness, saving of time, and in the production of a better article. What I claim as my invention, and desire to secure by Letters Patent, is

Removing the elevated parts of embossed paper by means of an apparatus the principal parts of which consist of two rollers, substantially in the manner and for the purpose described.
